Roivios is developing a novel renal assist device called JuxtaFlow, which uses a patented technology to improve renal function and decrease venous congestion in patients at elevated risk of acute kidney injury. The device delivers a mild suction into the renal pelvis, offering a treatment solution for fluid overloaded patients. Roivios competes with other medical device companies in the industry such as NxStage Medical Inc., Fresenius Medical Care AG & Co. KGaA, and B. Braun Melsungen AG.
